What else can I help you with?
A reaction which forms a solid product is an example of a?
precipitation reaction
Is Pb(NO3)2 2KI PbI2 2KNO3 neutralisation or precipitation?
Pb(NO3)2 + 2KI ==> PbI2 + 2KNO3 is a precipitation reaction. The PbI2 is insoluble in water and will precipitate. It is NOT neutralization, because you do not have an acid reacting with a base.
When calcium carbonate and hydrochloric acid react bubbles form. How do you know a reaction occurred?
You can tell that a reaction occurred because you observed the formation of bubbles, which indicates the release of a gas (carbon dioxide) as a product of the reaction between calcium carbonate and hydrochloric acid. The appearance of bubbles is a clear sign of a chemical change taking place.
Can the combustion reaction CH4 202---CO2 2H2O be classified as a precipitation reaction?
No. Precipitation is the formation of a solid in a solution during a chemical reaction. When the reaction occurs, the solid formed is called the precipitate, and the liquid remaining above the solid is called the supernate. Obviously CH4 + 2O2 = Co2 + 2H2O - in other words 1 methane + 2 oxygen = 1 Carbon Dioxide + 2 water - Does not form a solid in a solution so can not be a precipitation reaction.
What chemical change occurred in the following reaction Mg2 plus (aq) plus 2OH and minus(aq) and 10230 Mg(OH)2(s)?
In the reaction, magnesium ions (Mg^2+) reacted with hydroxide ions (OH^-) to form solid magnesium hydroxide (Mg(OH)2). This is a precipitation reaction where a chemical change occurred resulting in the formation of a new compound (Mg(OH)2) from the ions in solution.
What does this indicate about the reaction that took place in the beaker?
The formation of white precipitate indicates a chemical reaction occurred in the beaker that resulted in the precipitation of a solid product from the solution.
What chemical reaction causes precipitation?
This is a precipitation reaction.

What chemical change occurred in the following reactionMg2 plus (aq) plus 2OH(aq) Mg(OH)2(s)?
This is a precipitation chemical reaction.
Is there a precipitation reaction between potassium sulfate and strontium iodide?
Yes, a precipitation reaction occurs when potassium sulfate and strontium iodide are mixed. Potassium sulfate and strontium iodide react to form strontium sulfate, which is insoluble in water, leading to its precipitation as a solid.
How we know a chemical change has occurred when burning a candle?
Burning is a chemical reaction, an oxydation.
Why are precipitation reactions also called double displacement reactions?
They aren't. Double displacement (metathesis) sometimes forms a precipitate, but not always, and it would be silly to call it a "precipitation reaction" if no precipitate was formed. Formation of a precipitate is, however, one way to tell that a reaction has occurred. If everything just stays in solution, then it's meaningless to call it a "reaction" since there has been no change. The evolution of a gas is another method for determining that a reaction has occurred, as is a change in color (this often indicates a change in oxidation state as well, though not always).
A precipitation reaction is a reaction between two aqueous solutions that results in the formation of a compound. Answer?
A precipitation reaction contains two aqueous reactants, one aqueous product, and one solid product. A precipitation reaction will produce an insoluble product.
What is a ''non'' reversible reaction?
A non-reversible reaction is a chemical reaction in which the products cannot readily revert back to the original reactants. This means that once the reaction has occurred, it is not easily undone under normal conditions. Examples include combustion reactions and many precipitation reactions.
What is precipitation reaction reaction?
A precipitation reaction is one in which two solutions react to form an insoluble solid called a precipitate and a precipitate is an insoluble solid which is formed on mixing certain solutions.
How does a chemical equation show that a chemical reaction has occurred?
A chemical equation shows that chemical reaction has occurred as new substances have been formed from the reagents. A chemical equation has two sides before reaction and after reaction, if there is any change from the before reaction side to the after reaction side, it indicates that a chemical reaction has just occurred.
